FCS measures the
in vivo mobility of Chs5 complexes in the cytoplasm. FCS analysis was performed on the GFP and Chs5‐GFP in the presence or absence (ΔΔΔΔ) of the ChAPs. 10–20 FCS measurements were performed for each condition using different cells and representative curves are shown. The ACF of free GFP is fitted with a one‐component anomalous diffusion model. The ACF of Chs5‐GFP in both WT and ΔΔΔΔ background was fitted with a two‐component diffusion model. The residuals assess the quality of the fit. Note the ChAP deletion affects the diffusion of the slow component of Chs5 only mildly. Estimated diffusion correlation times, diffusion coefficients, and fractions are shown in Table
